How does the ABS relay work on a GMC?

The ABS relay supplies battery voltage to six valve solenoids (RF dump/isolation, LF dump/isolation, and rear dump/isolation). The Electronic Brake Control Module (EBCM) microprocessor applies the grounds needed to activate each solenoid. The low side of each solenoid coil has a feedback circuit to the EBCM microprocessor.

What happens if the EBCM relay circuit fails?

Traction control helps keep your car going in a straight line and ABS prevents your brakes from locking-up and sending you into a skid when you hit the brakes. So, having a bad EBCM problem can be a serious safety hazard for your vehicle as it can disable both of these systems. What Causes the EBCM Relay Circuit to fail?
